title: Multi-microelectrode investigation of monkey striate cortex: link between correlational and neuronal properties in the infragranular layers.
abstract: Recordings were taken from infragranular layers of area 17 of anesthetized monkeys with an array of 30 microelectrodes matching about one hypercolumn. From intracortical spike-train correlations, the novel neuronal property "delay scale position" related to retino-cortical delays, was derived. Relationships were established to the degree of spike isolation and to classical response properties. Direction selectivity, spike rate, spike-isolation quality, delay scale, and color selectivity could be linked to an underlying factor upon which the latter variables depend in a fixed way. Neurons with similar factors were characterized by non-delayed correlations. The link was more strict in layer VI than in layer V, and it was related to the parvo/magnocellular subdivision of the visual system.
